Ber7,

You amaze me with your use of graphics in SMath. I'm a civil engineer and use SMath for calculations just like this but without the pictures.

Could you post your SMath sheet in a zip file so I can see how you do it? I don't use RAR. Thanks.

Ed

Hello.

This is very nice. I am civil ingenieer & I will use it. Thanks.

However it is dangerous to use the function x>Lf.
I found it out in my own beam programming.

When changing direction of concetrated forces, the graph of shearing force has to jump once up & once down.

And for the following input it does not!

It seems to me, the function x>Lf does not work correctly each time.

Regards Olik

Thank you! This is already fixed and will work correctly even without eval function into the next SMath Studio release.

Regards.

Thanks to all. The eval function seems to be a good way.
And if You fix this little bug, it will be the best.
